S?he could also write such a macro from scratch and post the result here
together with a suitable name.

Who cares? The overhead for removing and adding a hook (with all the
necessary protection) is just as high.

We agree here.

That's the way to go, yes. The question is rather one of how to avoid
confusing users when we have, for example, a `temp-buffer-setup-hook'
and a `plain-temp-buffer-setup-hook' and BOTH get run when we invoke the
inheriting macro.
